I run IROK's 39.5, and have no idea how much lift, if you measure stock to now its about 12-14" higher. not sure if you will get 37's with out trimming or bumpstopping, I do not belive in bumpstopping just to get bigger tires. I run a 97 sport 4door. I cut hte rear fender wells out and added 12" to the center to run 39.5, I just finished trimming my front fenders after grabbing them for so long. now it looks like the 39's came stock LOL. I also use it as a daily driver. I have learned as you soon will, once you start putting all this stuff on your rig, like 37's bigger axles, roll cages, and stuff like then you tend to run harder trails, which in turn leads to carnage. SO as good advice, buy another vehicle for your daily if you are planning this. You will be happy you did, when you break on the weekend, nothing is open until Monday, or you have to pay someone to fix it, that can not get ot it for a week, and you have to drive it to work, have fun walking. Just my 2 cents.
Oh, and yes it is still my daily driver, I just didn't think about it until it was all done and I started breaking things,
